what is a dangerous level of bilirubin in adults

High bilirubin levels in adults could be a sign of an underlying health condition, such as jaundice, gallstones, and liver issues. Bilirubin is a yellowish substance in the blood that forms after red blood cells break down and travel through the liver, gallbladder, and digestive tract before excretion. Normally, total bilirubin levels between 0.2 and 1.3 mg/dL are considered normal for adults. However, different labs may have slightly different ranges for what they consider normal bilirubin levels. If bilirubin levels are higher than normal, it may suggest a problem that needs attention, but high bilirubin itself won’t usually need treatment. In adults over 18, normal total bilirubin can be up to 1.2 milligrams per deciliter (mg/dl) of blood. For those under 18, the normal level will be 1 mg/dl. Normal results for conjugated (direct) bilirubin should be less than 0.3 mg/dl. High bilirubin levels can be dangerous and can cause a yellowing of the skin and eyes, a condition called jaundice. However, the specific level of bilirubin that is considered dangerous may depend on the underlying condition and should be determined by a healthcare provider.
